1.3. Main ON/OFF Switch/Keypad ON

When the switches on wire number 22 connects to the battery
voltage to the ETAC (A2) pin J11-1, this powers up the ETAC
(A2) for start of communication to the transistor controller
(A1). A voltage of volts from the resistor (PTC R1) 1.0 to 1.5
volts less than battery voltage is provided to the positive side
of arm angle A switch (S24), arm angle B switch (S25), and
the normally closed lift limit switch (S36) to the transistor
controller (A1) pin J5-15.
